ABSTRACT:
A hydromassage bathtub for domestic and therapeutic applications. The bathtub has a two level bottom wall defined by two successive surfaces sloping slightly towards the drain pipe area and joined to one another by a transverse ramp of slight extent, a front inclined wall having a centrally located depression facing the lower portion of the back of the user, an essentially vertical end wall opposite the inclined wall and two essentially vertically extending lateral walls. Longitudinal passages secured to the outside surface of the bathtub along the lower region thereof and extending essentially tangentially to the lateral walls, to the inclined wall and to the end wall, for circulating compressed air emanating from blowers. The compressed air is also distributed through inwardly extending branches connected to the lateral passages, the branches being located underneath the bathtub and following the transverse ramp. A plurality of apertures leading from the air distribution system to the inside of the bathtub distributed evenly around the periphery of the bathtub slightly above its bottom wall but in the area where the lateral walls, inclined wall and end wall merge into said bottom wall there being at least two apertures leading from the branches to the lower region of the transverse ramp and at least two apertures at spaced apart locations in the depression whereby air under pressure is injected inwardly and slightly upward from all sides into the body of water contained into the bathtub for producing the desired hydromassaging effect.
